Application filed January 11, 1912. Serial No. 670,590.

To all whom it may concern:

Be it known that I, LOUISA BLAKE, a citizen of the United States, residing at Worcester, in the county of W'orcesterand State of Massachusetts,- have useful Snow-Scraper, of which the followv objects of this invention are to provide elficient means for scraping the bulk of the snow from a street and then cleaning the surplus from the surface thereof; to provide meanswhereby the scraping device can be conveniently turned from side The principal to side so as to leave the snow at either side of the vehicle and also to construct it so that it can be raised out of operative position in a very simple and convenient manner; to provide a cleaning-brush of such a character that it can be operated positively from the power used to drive the vehicle, and at the same time can bemoved bodily into a diagonal position at either side without disconnecting it from the power; and to provide an automobile snow scraper of such a character that it can be used for snow scraping purposes when running backward, whereby the vehicle can be run at comparatively high speeds when not in operation for scraping snow without changing the ordinary forms of transmission now .in i use. The invention also involves improvements in various features of the invention as will appear hereinafter.

Reference is to be had to the accompanying drawings in which- Figure 1 is a plan of a snow scraping vehicle constructed in accordance with this invention; Fig. 2 is a side view thereof; Fig. 3 is a plan of the mechanism for directly operating the. scraping blade with the top part of the vehicle removed; Fig. 4. is a. similar view with, the arts in a differentposition; Fig. 5 is a side elevation partly in section of the blade supporting operating mechanism; Fig. 6 is a similar view on enlarged scale of a portion of the parts; Fig. 7 is a side view of the bottom of the turret for operating the scraper blade; Fig. 8 is a sectional view on the line 8-8 of Fig. 6;-

is a sectional view on the line 115-11,. of

'Fig. 10; Fig. 12 is a sectional view of the brush casing and connected parts on the,

invented a new and .--ing blade. It is. adapted of the cleaning brush and connected parts; Fig. 10 is a sectional-view. thereof on the line 10-1O of Fig. 9; Fig- 11, a

The-eyebolt 34 is'in such move in a circle about the shaft 23.

line l212 of Fig. 10; and Fig. 13 is a sectional view on the line 1313 of Fig. 11.

The invention is shown in a form in which a well-known type of motor vehicle 15 is employed havingv the usual motor 16, transmission 17 and steering wheel 18. Mounted adjacent to this steering wheel but at one side thereof, and facin backward is a seat 19 for the operator. e can operate the vehicle while seated on this seat either to drive it backward or forward. In going from place to place the vehicle is intended to be driven forward in the usual manner, but in scraping snow it is intended to be driven backwardly. For this purpose the vehicle is provided with a vertical turret 20. This has a bottom circular flange 21 which fits under clips 22 arranged in a cirdo on the floor of the vehicle. The turret is provided with a vertical shaft23 fixed to it extending dowiithrough the bottom ofthe vehicle and having a pair of arms 24 at its lower end at an angle to each other. Each of these arms is connected by a link 25 with one arm of a lever 26 which is pivoted to a bracket 26 on the frame. Also fixed to the frame of the vehicle is a metal piece 27 having a central bolt 28 thereon provided with a head at the bottom. Connected with the ends of the levers 26 is a horizontal plate 29 provided with an arcuate slot 30.

enlarged below to receive the headed bolt 28 and be guided that when the shaft 23 is turned by rotating the turret on its own axis the lovers 26 will swing the plate laterally as guided by the bolt 28 and slot 30.

Pivoted on horizontal pivots near the front of the frame 29 is a swinging frame 31.- At the end this carries a scraping blade 32 having an upwardly extending hood 33 for preventing the snow from passing over it and being deposited behind it. Mounted on the frame 31 isan eye-bolt 34: connected b a chain 35 with the lever 36 pivoted wit in the hollow turret 20. This lever is adapted -to swing back and forth inthe turret to raise and'lower the scrapto be held'in its ad usted positionstby a spring-catch 37. position that as the frame swings the eyekbolt will always 11 this way the end of the lever 36, which of course moves with theturret, will always be thereby. It will be obvious I directly over the eye-b0lt and the chain will be substantially vertical. The turret is held in its adjusted positions by a foot catch 38 adaptedto enter slots 39 in the flange 21.

The motor is arranged to drive a horizontal shaft 41 by an extra chain 40. On this shaft is pivoted a frame 42- on which is' mounted a second horizontal shaft 43 driven from the shaft 41 preferably by bevel gears. At the other end of the frame 42 is a vertical shaft 44 driven by the shaft 43 by gearing which comprises a double bevel gear 45. This shaft 44 is located at the-center of the vehicle and the frame 42 is provided with a circular flange 46 concentric with the shaft 44, on which flange is mounted to swing a casing 47. This casing carries a train of gearing 48 which has a bevel gear 49 at the top meshing with the bottom half of the double bevel gear 45. This train of gearing drives a double rotary brush 50, mounted to rotate horizontally in this casing.-

Adjacent to the operators seat 19 is a handle 51 on a vertical rod 52 which is provided with a pair of arms 53 on opposite sides thereof connected b links 54 with the brush casing 47. By swinging this arm 51 this casing is swung about the axis of the shaft 44 as a center so as to give it any desired angle on either side as indicated in dotted lines in Fig. 9. On the rod 52 is a notched disk 55 which is engaged by latch 58 to hold the brush casing in adjusted positions. Mounted adjacent to the seat 19 also is a foot lever 56 connected by link 57 with the frame 42 and adapted to swing the frame about the shaft 41 as a Center so as to raise the brush off the ground whenever desired. The usual brake lever 59 is shown at the rear of the seat 19.

From the description of the the operation will be obvious. observed, however,

parts given It is to be that as the operator faces backwardly on the vehicle he is in position to operate the device conveniently as a scraper and sweeper, and that all the parts necessary for him to operate in order to raise the brush or scraper or turn them from side to side are within convenient reach. The turret is designed to be operated by both hands and the lever 36 can be. operated simultaneously with one hand. WVhile operating these parts the locking latch 38 can be operated by the operators foot. The brush is raised and lowered by the operators foot and is swung from side to side by hand. It is obvious, of course, that these various adjustments occur ordinarily at long intervals and chiefly when turning from one street to another or reversing on a street.

Although I have illustrated and described a preferred embodiment of the invention, I am aware that many modifications can be made't-herein by any person skilled in the art without departing from the scope of the invention as expressed in the claims. Therefore I do not wish to be limited to all the details herein shown and described, but

What I do claim is:
